Swift is a multi-tenant, highly scalable and durable object storage system that was designed to store large amounts of unstructured data at low cost via a RESTful http API. “Highly scalable”, means that it can scale from a few nodes and a handful of drives to thousands of machines and dozens of Petabytes of storage. Swift is designed to be horizontally scalable–there is no single point-of-failure. Swift is also ideal for storing and serving content to many, many concurrent users - a charateristic which differentiates it from other storage systems.
